I have a macbook pro a1286, that i believe is mid 2009 or mid 2010, not sure because i bought it second hand with this problem. The guy i bought it from said it was a mid 2009 but i entered the serial number in online and a website told me it was a macbook pro a1286, mid 2010. Anyway, It works completely fine on an external monitor but when its not plugged into an external monitor there is no image. I thought maybe the screen was bad so i bought a new one and replaced it but it didnt help at all. When i turn the computer on you can see the screen turn on sort of, it goes from gray to black, with no back light and no image at all, even with a flash light, and when i power it off you can see the black fade. Its hard to explain, i hope someone understands what im saying. Anyone got any ideas? I dont want to do anything drastic if its not necessary, such as a reflow or something.
